The service trial will kick off by middle of 2014 and will be limited to Corpus Christi, Tex., initially. Dish will be installing either outdoor routers or indoor units for customers who want to take advantage of the TDD-LTE airwaves riding on Sprint’s 2.5 GHz spectrum. The companies plan to expand into other markets after that.

At the time, Dish and Sprint were engaged in a bidding war for broadband wholesaler Clearwire, whose vast holdings of 2.5 GHz spectrum licenses was the prize. Sprint eventually won out with a bid of $5 per share for the half of Clearwire it didn’t already own. Sprint has since begun boosting the speed and capacity of its LTE network using the 2.5 GHz spectrum in addition to its recently repurposed 800 MHz airwaves and its ongoing LTE deployment in the 1900 PCS band.

“Results from the first phase of our trial were encouraging,” said James A. Hyde, CEO of nTelosHoldings Corp., said in a statement. “Expanding the trial will give us the opportunity to stress test the network for coverage and reliability, and to further evaluate the viability of a full commercial launch.”
